Safety instructions

3.9 Handling solvents (including solder, adhesive and flux)

Cleaning organic solvents, such as isopropyl alcohol (IPA) and absolute ethanol are used for the maintenance

of this machine (including optional units). Additionally, the solder paste printers, dispensers, and some hybrid

placers and flip chip bonders use solder, flux, or bond, etc. during normal production. Since many of these

materials include organic solvents, great care should be taken when handling them.

Cautions on handling solvents

1. Hazards to human health

Organic solvents constantly vaporize and contaminate the surrounding atmosphere. Inhaling or coming in contact with

organic solvent vapor may cause serious damage to human health.

2. Flammability

Organic solvents are highly flammable substances and can easily catch fire if handled improperly.

3. Adverse effects on machines

Some kind of solvent may deteriorate parts used in the machine, electric cable sheathes, and other resin parts.

To prevent accidents caused by solvents

1. Be careful not to inhale toxic vapors of solvents for extended periods.

2. Do not use solvents near fire or flame. Keep solvents away from flame or fire.

3. Use only the specified solvent in the correct manner. Do not reuse any solvent repeatedly, and do not mix with other

solvents or chemicals.

4. Check the contents of the safety data sheet (SDS), thoroughly notify work personnel of toxicities of included chemical

materials and measures to be taken in case of an accident, and take necessary countermeasures.

5. Use appropriate safety gear (safety goggles, protective gloves, and respiratory protective devices) corresponding to the

solvent or material types.

6. See the safety data sheet (SDS) for how to dispose the solvents and the cloths used for wiping off the solvents.

CAUTION

If no safety data sheets (SDS) are supplied with solvents or materials you have purchased, be sure to acquire the

safety data sheets from the suppliers.

3.10 Handling the laser

In this machine (including optional units), there are portions using the laser, such as a sensor and barcode

reader.

CAUTION

The laser to be used by this machine is class 2 (visible light and low output) at a maximum.

Knowledge and information about laser

1. Harmful to human body

Never look at the laser directly even when it is weak. In particular, if the laser is irradiated to an eye for a long time,

this may cause serious injury.

2. Reflection of laser

The laser is reflected by a glass or metal surface. Pay special attention to the reflected laser light during maintenance

work.

To prevent accidents caused by laser

1. Do not align your eye with the laser height so that you do not look at the laser directly.

2. Wear safety goggles during work, when necessary.

3. Shield the laser during work, when necessary.

Safety instructions

3.11 Handling grease and oil

Grease or oil is used for the operating axes of this machine. When performing the lubrication work, strictly

observe the cautions shown below.

Cautions on handling grease and oil

1. If grease or oil enters your eye or sticks to your skin, this may cause inflammation. Be sure to wear safety goggles and

protective gloves during work. Additionally, if you swallow grease or oil by mistake, this may cause vomiting or

diarrhea.

2. If grease other than that specified is used, this may cause damage to the machine.

3. If grease with different characteristics is mixed with proper grease, this may cause the machine performance to lower.

4. Be sure to cap tightly after use to prevent entry of dust or water content. When storing the grease or oil, avoid the

direct sunlight, keep it away from a fire, and store it in a dark place.

NOTE

When the safety data sheet (SDS) about the grease or oil that is used for the maintenance wok is needed, contact

YAMAHA or your distributor.

3.12 Handling batteries

Batteries are used for some motors of this machine and the optional uninterruptible power supply (UPS).

Cautions on handling batteries

1. Do not disassemble the battery or touch its inside. Otherwise, electrical shock may result.

2. Do not over-heat or apply a strong impact to the battery. Otherwise, fluid leakage, explosion, or heat generation, etc.

may result. Never use the battery, to which a strong impact has been applied, such as dropping to the floor since its

battery fluid may leak.

3. Only engineers who have the experience and knowledge about electrical work are allowed to replace the battery.

4. The battery may discharge naturally. When purchasing a spare battery, do not store it for a long period and prepare it

one to two months before the scheduled replacement work. Additionally, when storing the battery, avoid a place where

the temperature increases and be sure to store it at room temperature.

NOTE

When the safety data sheet (SDS) about the battery is needed, contact YAMAHA or your distributor.

CAUTION

For details about how to handle the UPS, see the user's manual prepared by the manufacturer that is supplied with the

UPS.

CAUTION

When disposing of a battery, dispose of it in compliance with the laws and regulations of the country where the

machine is used. If you have any questions about disposal of the battery, please contact YAMAHA or your distributor.

3.13 Handling heavy objects

This machine (including optional units) may require the operator to handle heavy objects during work. (For example,

magazine or cassette replacement) If you hold up a heavy object in an unnatural posture, this may cause damage to your

back. Additionally, if you fall a heavy object to your feet, this may cause serious personal injury. Or, falling a heavy

object may cause damage to the magazines or internal tray components.

Cautions on handling heavy objects

1. Be careful not to take an unnatural posture during work. In particular, be aware that you may take an unnatural posture

easily when holding up a heavy object from a low place. It is recommended to hold up a heavy object by bending and

stretching your knee instead of bending your waist or prepare a cart with an appropriate height when necessary.

2. When a handle is provided, such as magazine and cassette, hold the handle securely and perform the work.

3. To prevent personal injury caused by heavy object dropping, be sure to wear safety shoes.

CAUTION

When heavy object handling standards are deﬁned at the customer's factory, be sure to follow the standards during

work.
